i haven't played since latest balance patch so my comment might be outdated 1v1 is good since wr have one of the best grabs and reliable its definitely not meta for node war but you can play certain roles well (cannon def/anti cannon/flex)
While i do love your combos, to me your opponents seem a bit mediocre. Like honestly sorc was Q blocking etc..id like to see if you can pull it off VS players who know how to pvp
depends on what is off cd but my go to grab combo is : grab > fwslash > cswap > armor break > full charge reckless > rmb cancel > heaven's cleave > overwhelm > slashing > ankle > 10% pulverize
